digitalmars.D.learn - Make function nothrow

reply ref2401 <refactor24 gmail.com> writes:
There are functions in Phobos that do not throw but they are not 
marked as `nothrow`.
When I need to call them from my `nothrow` code I do this:

void foo() { /* I won't throw, honestly. */ }

void bar() nothrow {
	scope(failure) assert(false);
	foo();
}

The question is: Is it ok to do such thing or should I just stick 
with try {} catch() {}?
Thank you.

There is assumeWontThrow which terminates if an exception is indeed thrown:
